Can so!
And I happen to think (and hope) that they will, in the matter of gay marriage.
I hope everyone can see that Krugminator is arguing for gay marriage, not for interracial marriage. But the only consistent position is mine. Do you oppose things like:
Your locality being forced to issue gay marriage licenses
Your private club being forced to have openly gay people teach your boys and young men
Your church being forced to comply with non-discrimination laws -- that is, to employ openly gay people (and at an acceptable rate to prove they're not discriminating)
You personally being forced to rent to gay people
Your religious college (BYU, Liberty College, Hillsdale College) being forced to admit homosexual students, hire homosexual professors, de-segregate male and female dorms, and of course to allow and celebrate homosexual cohabitation
Your business being forced to not take any action -- or even inaction -- intolerant of or discriminatory towards perverts?
If you want to oppose this dystopian future, and to be consistent, you have to oppose all laws against discrimination. There is no halfway, middle-ground, holding position that can stand. The analogy used by the gay mafia, like it or not, is actually perfect. It's very compelling. If you accept the proposition that is was righteous and wonderful and a step forward for progress for the state to start forcibly blessing miscegenation, and forcibly prohibiting anyone from exerting social pressure against such unions (by refusing to rent to them, refusing to accept their coupling as a legitimate marriage, making deed covenants prohibiting them from moving into their neighborhoods), well then that's end game. Just wave the white flag now. You've already lost.
Discrimination is a positive social good. The more discrimination the better. All discrimination -- that is, all private property rights -- must be legalized.
